Part 103 discussion

[radfordc]

When FAR 103 was first written, the limits were based on the then existing ultralights, many (but not all!) of which were converted hang gliders. So, part of the limits were based on existing designs (whether or not based on pilot's lying about their aircraft's weight).

Chuck Slusarczyk who makes the CGS Hawk told me this story. When the FAA was considering Part 103 rules they asked for input from the major UL manufactuers. Lyle Byrum of Quicksilver lobbied hard for the 254 weight restriction. Why...because that's what he thought a Quicksilver could weigh and he wanted other manufactuer's with heavier planes to be at a disadvantage. After the rule was put in place Chuck asked the FAA guy who ran the process what weight the FAA was ready to accept and was told 500 lbs.
